Not quite as dynamic a figure as I would have liked. Even reversing the position of the sword would have made it better.
I'm not sure that you could reverse it yourself without some serious work.
Here is a video of it with some commentary and a 360 view.

It is an excellently sculpted figure though. The details on the armour are fantastic making it look elaborate and unique while retaining the classic look of power armour.
There will be some very happy people out there now they can get their hands on Dorn.
All that is left now for the Primarchs are:
Sanguinus
The Lion
Alpharius
The Khan
So five more figures, six if you include the Emperor.
